metabolism
Cell metabolism involves a series of chemical reactions that break down nutrients to generate energy and produce molecules necessary for cell functioning. These reactions are catalyzed by enzymes and involve the transfer of electrons and rearrangement of chemical bonds, making metabolism a chemical process at the cellular level.
chemical energy
One important chemical activity that takes place inside a cell is cellular respiration, where glucose is broken down to produce energy in the form of ATP. This process occurs in the mitochondria and involves a series of complex chemical reactions.
We call this collection of chemical reactions metabolic reactions or metabolism.
In a cell, chemical reactions that involve energy include cellular respiration, where glucose is broken down to produce ATP, the cell's energy currency. Another key reaction is photosynthesis, where light energy is converted into chemical energy in the form of glucose. Both processes involve complex series of reactions that require and release energy.

The organelle responsible for controlling all chemical reactions within an animal cell is the nucleus. It houses the DNA, which contains the instructions for cellular activities, including the regulation of chemical reactions. The nucleus also controls the synthesis of proteins that are essential for carrying out these reactions.
The correct voltage of a chemical cell at equilibrium is zero. This is because at equilibrium, the rates of the chemical reactions within the cell are equal and there is no net flow of electrons, resulting in no potential difference.
Life is a complicated series of chemical reactions.
